Similarly, upper control arm 34 has upper leg 108 and upper leg 110 converging at upper core 112. The lower core 106 forms a bore 114, and the upper core 112 forms a bore, respectively (not shown in FIG. 5) configured to receive the lower and upper ball joints (see FIG. 8).

At the lower end the spring 50 is coupled to the lower control arm 32 by a spring bushing 116. The upper end of the spring 50 is configured to be attached to a vehicle, for example a vehicle body.

6 shows a perspective view of the portal wheel end 44. Portal wheel end 44 and portal wheel end 42 are substantially mirror images of each other. Thus, for brevity, only portal wheel end 44 will be discussed in detail. It should be appreciated that the details and features described for portal wheel end 44 are also applicable to portal wheel end 42.

The portal wheel end 44 includes a lower extension 118 and an upper extension 120 spaced from each other. With continued reference to FIGS. 1-5, the lower extension 118 and the upper extension 120 each extend in an outward direction towards the control arm assembly 36. In addition, the upper extension 120 also extends in the upward direction. Lower extension 118 is configured to engage lower core 106 and includes lower extending bore 122 to facilitate such engagement. Similarly, the upper extension 120 is configured to engage the upper core 112 and includes an upper extension bore 124 to facilitate such engagement. The ball joint can be inserted into the lower extension bore 122 and the lower core bore 114 to couple the lower extension 118 to the lower core 106. Similarly, the ball joint can be inserted into the upper extension bore 124 and the upper core bore (not shown) to couple the upper extension 120 to the upper core 112.

Portal wheel end 44 further includes a housing 126. Housing 126 includes an input gear (not shown) and an output gear (not shown). The input gear engages to have a shaft 48 and through this coupling receives torque from the half shaft 48. The output gear is coupled to the input gear and receives rotational input from the input gear. Wheel hub 128 is coupled to the output gear and receives rotational input from the output gear. Both the output gear and the wheel hub 128 are rotatable about an axis of rotation offset from the axis of rotation of the half shaft 48 and by an extension from the center axis of the module independent suspension 20. This offset of the rotational axis of the output gear and wheel hub 128 increases the height of the module independent suspension 20 and consequently increases the height of the vehicle to which the module independent suspension 20 is attached.

In the described embodiment, the vehicle body of the vehicle 130 is attached to the module independent suspension 20 in only four positions. The vehicle body is connected to the module independent suspension 20 at the upper ends of the springs 50 and 52 and at the flanges 84 and 86. The module independent suspension 20 configured in this manner can be easily attached to the vehicle 130 and easily removed.

8 is an enlarged view of an alternative embodiment 132 of a module independent suspension made in accordance with the teachings disclosed herein. In this figure, ball joints 134 are shown. The ball joints 134 are configured to couple the upper control arms 34 and 40 to the upper extensions of the portal wheel ends 42 and 44 and also connect the lower control arms 32 and 38 to the portal wheel ends 42. And the lower extensions of 44).

With continued reference to FIGS. 1-7, additional features shown in alternative embodiments 132 are the presence of spacer parts 136, 138, 140, and 142. These spacer parts are generally disk-like structures and made from metal materials. In other embodiments, the spacer parts may have any other suitable structure instead of having a disk like structure.

Each spacer part is configured to be installed in the subframe 22 and the flank parts 24 and 26. In addition, the spacer parts can be installed relative to each other to position multiple spacer parts between the subframe 22 and the flank parts. By placing one or more spacer parts between the subframe 22 and the flank parts 24 and 26, the width of the module independent suspension 20 can be increased to accommodate vehicles with different widths.

Each spacer part has a center bore extending through the center bore 137, the center bore 139, the center bore 141, and the center bore 143, for example. The center bores of the spacer parts are configured to align with the bores 60 and 62 of the subframe 22 as well as the bores of the flank parts. The presence of the center bores in each of the spacer parts and the alignment of the center bores of the respective spacer parts with the flank parts and the bores of the subframe are the left side 57 of the subframe 22 from the portal wheel ends 42 and 44. And a substantially unobstructed passageway for the extension of the half shafts 46 and 48 to the right side 58.

9 shows a bolt hole pattern for the subframe 22 that allows spacer parts and / or flank parts to be installed at different positions relative to the subframe 22. With continued reference to FIGS. 1-8, as shown, the left side 57 of the subframe 22 is shown having seven pairs of bolt holes extending into the left side 57. As also shown, each of the spacer part 138 and the flank part 24 has only four pairs of bolt holes. The four pairs of bolt holes of the spacer part 138 and the flank part 24 are configured to align with four consecutive pairs of bolt holes each on the left side 57.

When assembling the module independent suspension 20 or when assembling the alternative embodiment 132, the spacer 138 and / or the flank parts 24 configured in this manner may be located adjacent to the left side 57. Four pairs of bolt holes of spacer part 138 and / or four pairs of bolt holes of flank parts 24 can be aligned with any desired subset of four pairs of bolt holes of left side 57. For example, if a relatively high ride height is required a subset 144 where the bolt holes of the spacer part 138 and / or the flank part 24 comprise four pairs of bolt holes below the left side 57. ) Can be aligned. Conversely, if a relatively low ride height is required, a subset of the four pairs of bolt holes of the spacer part 138 and / or the flank part 24 includes four pairs of bolt holes above the left side 57. And may be aligned with 146. In this way the ride height of the vehicle using the module independent suspension 20 can be adjusted simply by attaching the spacer part 138 and / or the flank part 24 to the other bolt holes of the subframe 22.

Although the embodiment described depicts the left side 57 as having seven phase bolt holes, it should be appreciated that in other embodiments any suitable number of pairs of bolt holes in the left side 57 can be used. Similarly, more or fewer pairs of bolt holes may be provided in other embodiments of the spacer component 138 and other embodiments of the flank component 24.

10 is a flow diagram illustrating an embodiment of a method 148 of assembling a module independent suspension with portal wheel ends. With continued reference to FIGS. 1-9, in step 150, a plurality of spacer parts, such as spacer parts 136, 138, 140, and 142, are assembled on the left and right sides of the subframe, such as subframe 22. . When assembling the spacer parts into the subframe, the bolt holes formed in the spacer part (s) may be aligned with the bolt holes formed in the subframe or a subset of the bolt holes.

In step 152, flank parts, such as flank parts 24 and 26, are assembled to the spacer parts, which flank parts are located on opposite sides of the subframe 22.

In step 154, a cross member such as cross members 28 and 29 can be attached to the two flank parts such that the flank parts couple to each other. This configuration will improve the strength and stiffness of the module independent suspension formed as a result of the following procedure 148.

In step 156, a control arm assembly, such as control arm assembly 30 and control arm assembly 36, is assembled to the flank components. This may require assembling the upper control arm of each control arm assembly to mounting brackets located near the top of each flank part, and further, the lower control arm of each control arm assembly near the bottom of each flank part. It may be necessary to assemble to the mounted mounting points.

In step 158, portal wheel ends, such as portal wheel ends 42 and 44, are assembled to each control arm assembly. This will position the portal wheel end on opposite sides of the subframe.

In step 160, half shafts, such as half shafts 46 and 48, are assembled at each portal wheel end. The half shafts are positioned to extend through the flanks, the spacer parts, and the bores formed at the left and right sides of the subframe. The half shafts installed in this way are engaged with a carrier, such as carrier 54, and are ready to transfer the torque generated by the carrier to the end of each portal wheel.

In step 162, a fully assembled module independent suspension is provided for sale. Providing modular stand-alone suspension for sale as a single unit component allows end users to quickly and conveniently replace suspensions on the vehicle without the need for complicated assembly and / or disassembly of the separate components.
